To all whom it magftoncervt:

Be it known that we, Harrow lilnwaso ENSOR and Jomv SAMrsoN, both British subjects, residing at The Vicarage Hororata, Canterbury, in the Dominion of New Zealand, and 130 Tennyson street, Sydenham, Christchurch, in the Dominion of New Zea land, respectively, have invented new and useful Improvements in Headlights, of which the following is a specification.

This invention relates to the head-lights of motor-cars, motor-cycles and the like and refers more particularly to means for controlling the light when in traffic in order to obviate the glare or dazzling effect which would otherwise be experienced by those meeting the vehicle.

It is the object of the present invention therefore to provide simple and effective means whereby, at the will of the driver, the whole of the light may be so deflected as to preventits rays from coming in direct coutact with the eyes.

In order that the nature of the invention and its construction may be clearly under stood, reference will now be made to the accompanying sheet of drawings, in which Figure 1 is a front view of .a lamp equipped in accordance with the present invention, the latterbeing 'in inoperative position.

Fig. 2 is a side view of the same.

Fig. 3 is a longitudinal section through the lamp, upon a somewhat larger scale than the preceding figures, the device being shown in full lines 111 its operative position, while the inoperative position is indicated in dotted lines. a

Fig. 4 is a side view of a portion of the lamp, illustrating a means of operating-and controllin the, parts.

(1) -is which is contains the usual lamp (2) and reflector (3) all as customary.

- According to the present invention the -lamp-bod is provided with a hood or cowl (4:) suite 1y formed from sheet metal or other suitable material and adapted to extend around and inclose the upper portion of such lamp-body.

The said hood (4-) is attached to the lamp-body (1) by means of a pair of laterall disposed pivots arranged one on either si e thereof and adapted to permit of such hood either occupying its normal or inop- Specifieetion of Letters Patent.

. erative position, as in Figs. 1 and 2, and in dotted lines Fig. 3 or being rocked or turned to a suitable angle in a forwardly angle in a forwardly direction, as indicated in full lines Fig. 5, in order-that such hood may intercept and deflect those rays of light which would otherwise extend upwardly at; an angle from the front of the lamp-body.

This pivoting of the hood is preferably effected by providing at the required points upon the lamp-body, one on either side thereof, apair of laterally projecting trunnions (5) which are recelved in suitable bearings in the hood which bearings may conveniently consist bf a pair of outwardly projecting; sleeves (6) attachedto such hood.

Accor ing to the present invention also within the lamp-body and arranged at a position vertically beneath the lamp (2) is a flap or sector(7) of sheet metal.

The said flap is attached by means of a.

suitable hinge (8) to the reflector or other suitable portion of the lamp-body in such a manner as to permit of such fia being turned in a vertical plane upon its said hinge (8).

(7) when in its normal position, as shown in Fig. 1 and in dotted lines Fig. 2, will overlie and fit closely against the surface of the lower portion of the reflector and such flap is suitably polished or otherwise prepared in order that, when in such position it may serve the ordinary purpose of the portion of the reflector which it covers.

When required to perform its special purpose however, the said flap is turned upon its hinges (8) into such a, position as to r0- ject forwardly at an angle with the sur ads of the reflector, as shown in full lines Fig, 3.

When in this operative position the flap The arrangement is such that the said flap serves to reflect or throw upward within the lamp-body those rays of light which would otherwise become concentrated upon the lower )ortion of the reflector and be projected orwardly thereby.

The means emplo ed for operating the flap (17) consist pre erabl of a horizontal spind e 9) mounted in t e portion of the lamp-boy in rear of the reflector, such spindle (9) being provided with an arm (10) y which is loosely received within a strap or saddle (11) attached to the rear side of the flap all). The arrangement is such therefore t at upon the spindle (9) being turned Q 7 menace v in one direction the arm (10) will engage the rear surface of the flap and thus cause the latter to turn upon its said hinge into its operative position as shown in full lines "Fig. 3, while by turning the said spindle in c the other or reverse direction, the arm (10) will engage the strap (11) and thus return the flap toits normal or inoperative position as indicated in dotted lines Fig. 3. For the purpose of permitting of these 1novements the reflector (3) is formed at the required position with a suitable slot or opening (12) through wh ch. thesaid arm (10) and strap (11) maypass. In lieu of this construction any other suitable means may be employed for operating the flap and such means may, if desired, includea suitable spring or the equivalent adapted to turn the flap in one direction.

Suitable means are employed also for causing the hood l) and flag (7) to turn in their forwardly or rearwaruiy directions in unison. As here shown Fig. 4 such means consistof an arm (13) upon the spindle (9) which is connected by means of a link or connecting rod (14) with a similar arm (15) upon onset the sleeves (6) one or both of such arms being preferably adjustable axi-' ally in order to permit ofthe required set ting of the hood and flap in relation to each other after which such arms are adapted to be locked in placebymeans oi set screws (16) or the like. Upon the spindle (9) or sleeve (6) is provided also another arin "(17) adapted to be connected by means of a connecting-rod or the like (18) with a suitable hand-lever, foot-pedal or other means of manipulation operable by the driver from his position within the jar.

These means of inter-connecting the hood and flap and enabling lsuch to be operated by the driver are givenzhowever merelyby Way of illustration andthe invent-ion must 1 not therefore be confined to such but inv From the foregoing description therefore it will be understood that upon the hood (4) and flap (7) being turned into their forward or operative positions the former will intercept and throw-downward upon the road the light which would otherwise proceed at an angle upwardly and forwardly from the upper portion of the lamp-front, while the action of the flap is such as to reflect upward within the lamp-body those rays which, partly as the result of the action of the hood, would otherwise become concentrated upon. the portion'of the reflector beneath the lamp (2). We claim Means for the purpose indicated comprising the combination with a lamp-body, a reflector and lamp contained therein, of a hood pivotally mounted upon the exterior of said lamp-body and adapted when turned in aforwardly direction to intercept and throw down the'light issuing from the upper portion of the lainp-front, a flap hingeably attached within said lamp-body and adapted to overlie the portion of said reflector'beneath said lamp, such flap being adapted;

when turned upon its said hinge in a for" wardly direction to extend at an angle with said reflector and tothrow upward within the lamp-body the rays of light beneath said lamp, and means whereby said hood and said flap may be caused to turniin' unison into Grain OARLYN CoArns, Sinner Janus TimLEAvEN.
